To al?, whom t muy cof/wem: i I y f Be it `known that we7 elosnrn ALFREDlvERELL, Emmer Pinironnon, and Unire PLOURDE, all British subjects,`residing at Quebec city, fSte. Anne yde Beaupre, Ste. Anne de Beaupre7respectively, all in Itho Province of Quebec, Dominion of Canada,

have invented certain newand useful inn provenients in ,automatic Streetand @tation indicators; and we do hereby declare that the following is afull, clearg and exact de` vide a device of this character that maybeoperated roin` anysuitahleplace'on the car, such as' inthe rear. wherethe conductor usually stands. 1` ,K

The invention will be readily understood from the accompanying drawingsand following description,` in which like" numerals oi? referenceindicatecorresponding parts in each ligure. In the drawings?? e e Figurel, is a front elevation oi the casing containing theldisplay sheet andoperating mechanism.

Referring to the drawing;y l` indicates casing'containing two superposedhorizontal shafts 8 which are journaled in suitable brackets mountedtherein and carry drums y the upper E' will be ,positively driven, one`drum winding `by the bracl-ret ported..y

a horizontal v.sl/rait 10, adapted to he yrotated.

stepby step by means of a pawl-and-ratchety device (not shown) or`conwentional.type

which is enclosed in a `casing 1l loosely mounted on the end oishatt l()and in which an operating lever 1Q is fitted; Lthe arrangement beingsuch that when said lever is swung in onedirection (ioreiainple, fromitsy 'full-line position to its dotted-line position,

l? 3.), the pawleandfratchet device will `turn shaft lOfonc step inthesame direction.

This lmovement of Vvthe. shaft is transmitted through interineshinggears 9. and. Sto the 'lower vdrum shai't Enf onr which gear 8 isymounted7 saidsha'ft 3? being provided withpa second gear -7 which isconnected through an intermediate wear (j with a similar gear Ton inshaft, so that both drums 3 up and the other Adrinn unwinding the disiplay sheet 2l." Thefinterinediate gear 6 is loosely mounted on a stubshaft v `carried The operating lever "l2 projects through a f slot 1B (Fig. 3) in the top wall of the'casing l and is provided adjacent its'tree end with e a handle lll, vby means 'offwhichfit may be f directlyshifted.

f to aetuate' said lever from a distance-'for 4instance from therearioi2the car where the yconductor usually stands; and with thatend in view,`the lever isiornied with a perforated lug l5 (Fig 6) to whichisconnected one end lt is ireierabie however. f

of an operating cord 16 orsimilar flexible element7 the other end or thecordbeing led l through an opening BO `iorined in Vaqcasing 27 (Fig.rloeatedin the rear part of the car. lThis casing 27, contains twopulleys 28` and 29 the latter of which is 'situated ad@` jacent opening30; and the oord 16 is passed over said pulley, then under a pulley 34:at-

To facilitate theoperation of lever 32, it may have suspended from it a handle 33., whichprojects downward through an opening in the bottom of casing 27 and aldash-pot 35 may 4also he connected with said vlever to cushion itsreturn movement when handle 253 isireleased.

" ln the construction illustrated,v the operating` lever 12 makes itsactive or driving' stroke whenmoving romlei't to rightfFig. 3) landy isreturned to its 4initial position by means of aspring;` il which issecured thereto atene end and at the other end to the bottom Wall efcasing 1.; this spring 21 also serving to return the lever 32 tonormaLposition, asavill he apparent. V:During the return movement of lever12,'fthepaWl-andratchet device moves idly but it is to be understoodthat, ii' desired, said device may operate during 'the return` strokeinstead et duringthe outward or initialstroke of the lever, or thatsuitable reversing means lmayhe employed in connection with the device'to enable the Winding action to take place on the drum previouslyactingto unwind 'theV sheet. i However, itis sufficient vfor vall .presentpurposes that the operating lever acts as` previously described,V thevprecise form ofratchet used not being material to the invention; In' anycase, the `sheet Winds up :onone drum and unvvinds from the other, theWinding` drum heingprovided With suitahle compensating means, forexampleV a conventional slip clutch, inorder to take care of theincreasing' diameter of one drumand the decreasing diameter of theother. The precise compensating 'means or device employed likewisev:terms no part of the actual invention and, hence, has not beenindicated.

lt Will be obvious trom` the foregoing that atfeach operation oirfthelever 12, Whether ell'ected directly by means of' its handle 14,

` for by pulling on the cord 16, the sheet'4 vvill be edafdistancesufficient to bring` the nextr street` orstation name opposite the.openingorl Window 2. ln` order to retainthe .sheet in position aftereachmovementrthereot, a "locking mechanism, here shown` as in the natureof an escapement isprovided. The operating' lever :12 is accordinglyequipped with across-rod or bar 20 (Fig. 3) to which are attached theupper ends ci? a.. pair oli.
